The team was created by Cheshire to help her on a mission. Its name was supposed to be a contrast to the name of their main enemies' team - Birds of Prey.
The team had four members at the start: Cheshire, Pistolera, Vicious and Termina. Termina betrayed the team shortly thereafter.
Cheshire went forward with only Vicious and Pistolera after that, and has lead several missions with them in pursuit of her goals.
